New PMU software version 122.0-beta is now available. What’s new: CANBus Export: Added new “Conditional” transmit mode Added “Merge Project” icon to toolbar between Open Project and Save Project. For more details, see the changelog. Download the update here: https://www.ecumaster.com/tv Sincer…

What’s the “watchdog mechanism” ?

long story short: the watchdog is a built-in safety timer that automatically restarts a microcontroller if it crashes; your code must check the timer constantly to prove it is still running, but if the code freezes and stops resetting that timer, the watchdog realizes something is wrong and triggers…

Would it be possible to show/switch fiew on the CANbus input window (for example can switch) on “test data” from hex view to binary view? Similar to windows calculator programming mode. Then i could see exactly which bit/bits i have actively selected with the start bit and bit count.

And does someone know how to invert a canbus input? As in, I set a single bit as boolean input but want it to be active at 0.

Any reason 122.0 was taken down from site?

We have received a few reports regarding issues with the watchdog mechanism that could result in a very rare scenario of PMU unexpected reset. We have recognized the issue and are testing the solution, so new firmware will be available in a few days.

Please advise what to do, the PMU-24DL in the car asking for software 122.0 and dont want to connect with 121 version… but 122.0 can not be downloaded anywhere

Which PMU Client version do you have? Could you share the screenshot showing these request?

i have 121.0 (exp1) and it asking 122.0 or newer [Screenshot 2026-06-10 112051]
